Specification of Letters Patent. P t t May 1 1911.

Application filed May 10, 1910. Serial No. 560,476.

To all whom it may concern:

Be it known that I, CHARLES F. W. LAsoH,

a, citizen of the United Statesof America, a and resident of Louisville,in the county of Jefferson and State of Kentucky, have invented certainnew and useful Improvements in Hose-Couplings, of which the following isa specification. r

This invention relates to hose couplings and particularly to adetachable hose coupling having novel means .for preventing leakage atthe joint between the sections of i v the coupling and the invent-ionfurther contemplates the provision of novel means for 15 securing thesections of the coupling together, novel means being also'provided' forcausing a release or disengagement of the means for securing the lockingsections of the coupling together.

A further ob'ect of this invention is to provide a coupling in which themembers of the coupling are provided with means for preventing movementwith relation to each other the same being provided with 111-t-erlocking devices which hold them against rotation. t

Furthermore, an object of this invention is to provide a hose couplingof the character noted which will prove strong and durable as well asefiicient and satisfactory Y in use.

With the foregoing and other objects in view, the invention consists. inthe details of construction and in the arrangement and combination ofparts tobe hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to" theaccompanying drawings forming part of this specification wherein likecharacters denote correspondin parts in the several views, in whichFigure 1 illustrates a view ,in elevation of a hose coupler embodyingthe invention; Fig.- 2 illustrates a central longitudinal sectional viewthereof; Fig. 3 illustrates a transverse sectional view on a ,linecorrespon'ding with the line 33 ofFig. 2;

4, 5 and 6 illustrate detail viewsv showingmodified arrangements of theends of the male sections designed to coact with. the seat in the femalesection; Fig. 7 illustrates a vertical sectional new of a hose couplingembodying a slight modification comared with that shown in Fig. 2; Fig.8 llustrates a top plan view of one ofthe members: Fig. 9 illustrates atransversevertical sectional view of the member shown in Fig. 8; Fig. 10illustrates an end view of the male member of the coupling; Fig. '11illustrates a perspective View of the said male member and a fragmentof'the female member; Fig. 12 illustrates a side elevation of the malemember; and Fig. 13 illustratesa perspective view of a fragment of thefemale member in section.

I In these drawings 10 denotes the pipe sect on having a nipple 11 towhich the hose is to be secured, the said section 10 having a nose orinner end 12, the internal bore of which is provided with an annularshoulder 13 on which theend of the pipe section 10 is seated, theannular shoulder being formed.

by recessingthe internal wall of the nose 12 which internal wall isthreaded to engage the threads of the pipe section 10. It will be seenfrom an inspection of Fig. 2 that the nose at its junction with the pipe10 has an annular shoulder 14 surrounding the pipe section 10 which isdesigned to be engaged by latches to be presently described.

A female section 15 has a threaded intermil wall 16 having connectionto'a hose, nipple orthe like, though the construction of this part ofthe said member is immaterial and it may be varied to suit particular requirements. There is a housing 17 provided with a flange 18 internallythreaded to engage threads on the member 15, and the member 15 is formedso as to provide a space 19 into which the tapered end 20 of the pipesection 10 extends, it' being understood that a gasket 21 coacts withthe surface 20 and is pressed by the force of the water into contactwith the tapered end 20 so that leakage at the joint between the maleand female member is prevented. It will be seen that the edge of thegasket is clamped between the housing and the inner edge of the femalemember whereby it is held in place.

The housing is provided with a series of radial slots 22' which aredesigned to receive the latches 23 which latches are slidable radiallyin order that their noses may engage the shoulder 14 as fully shown inFig. 2.-

gage the outer wall of the housing at points between the latches, thesaid spring acting to force the noses of the latches into engagementwith the shoulder 14. p

A cap 26 is secured to the housing by means of screws 27 andthe said caphas a flange 28 surrounding a'portion of the pipe 10 but standing fromit in order to form a space in which a collar 29 is slidable, the saidcollar surrounding the pipe 10 and serving to act on the latches for thepurpose of forcing their noses out of engagement with the shoulder 14.As shown in Fig. 2, the inner edges of the latches have cam surfaces 80which are acted onby the collar 29 in the manner indicated, that is toforce the said latches outwardly from engagement with. the shoulder 14.

From an inspection of the drawing, therefore, it will be observed thatwhen the members of the coupler are brought together into the positionshown in Fig. 2 and the collar 29 is moved to the position which itassumes in said figure, the latches are free to be acted upon by thespring 25 and forced into locked engagement. with the shoulder 14,whereby the coupling is effected. It will be observed also, from aninspection of Fig, 1, that when the sections of the coupling are inoperative relation, the interior mechanism thereof is protected againstthe access of dirt and foreign substances and'that such,a coupling willbe neat inappearance. When it is desired to disconnect the sections ofthe coupler, the collar 29 may be moved longitu; dinally of the pipesection 10 into engagement with the cam surfaces 30 of the latches andhence said latches will be moved radially out of engagement with theshoulders 14 when, as stated, the sections may be disconnected.

Fig. 4 illustrates the nose 12 as being of the same constructionas itappears in Fig. 2, except as to the means for attaching it to the pipesection. It is obvious that this at taching means is susceptible ofvarious modifications, and tliat the configuration of the nose may alsobe modified in various ways, for instance, as shown in Fig. 5, at 21*,and as shown in Fig. 6, at 21". On account of the manifest variationsthat may be made in the details of construction, I do not wish to belimited with respect to such details.

In the modification shown in Figs. 7 to 13 inclusive, I have providedmeans for pre venting rotation of the male member A with relation to thehousing B. In this form, I

have also produced-the male member A and the nose C integral instead ofhaving these elements separate as they are shown in Fig. 2. By taperingthe nose C, I form on the outer surface a beveled wall with which thewasher or gasket E c'oacts, the said washerv being interposed betweenthe male member and the female member The.

remainder of the structure shown in these Figs. 7 to 13 is the same asthat heretofore illustrated and described, except that the male member Ais provided with a'collar G which is' integral therewith and extendsfrom the side thereof, the said collar being provided with a series ofteeth H"w hich fit in the recesses I of the female member, the saidrecesses forming seats, as stated, for the teeth and when said teeth areseated therein, movement or rotation of the male member with relation tothe "female member is obviated. The collar A may be threaded on to themember A, or it may be secured by any proper means, after the member Lhas been placed thereon. The housing B in this connection is providedwith therecesses I in its wall, which are designed, to receive thelatches one of which is shown at J, Fig. 7, and which are similar in allrespects to those heretofore described, the said latches boin under thecontrol of the sprin K, an

caused thereby to engage the co lar G on the male member for the purposeof retain the collar L, and as these parts have been describedheretofore in detail the operation will, it is thought, he understood.

I claim- 1. In a coupling,

having an annular shoulder outside of the pipe section, a female memberhaving a housing, latches movable 1n the housing, a spring for holdinlatches in engagement with the shoulder, said spring being ofsubstantially triangular outline, the several angles thereof bearingupon the housing and a collar slidable on the pipe section for engagingthe latches.

several angles of said spring bearing upon said housing and a collarslidable upon said pipe-section and adapted to engage the cam surfacesof said latches.

4. In a hose coupling, a male and female .member having an interposedgasket, the said female member having a housing the latches slidable inthe a pipe section having a nose thereon, said nose latches slidable inthe housing, said latches having slots, a spring seated in the slots andline, the several angles thereof bearing upon said housing, sald latcheshavlng cam surfaces on their inner edges, a cap for the housing having aflange surrounding the male section but sth'nding a distance there from,and a collar slidable between the flange and male member and adapted toengage the latches.

, 5. In a hose coupling, a male and female member, a cone-shaped gasketforming a packing therebetween, a housing carried by the female member,latches having cam surfaces upon their lnner edges and slidable 1n thehousing, said housing havin slots for the reception of the latches, a soulder on the male -member engaged by the latches,
